Objective: To evaluate the accuracy of the automated oscillometric upper-arm blood pressure (BP) monitor Globalcare GCE603 for home BP monitoring according to the International Protocol of the European Society of Hypertension (ESH) revision 2010.
Methods: BP was sequentially measured in 33 adult participants and compared with a standard mercury sphygmomanometer. A total of 99 comparison pairs were obtained and analyzed according to the ESH international protocol.
Results: For the 33 eligible participants, the device achieved 80/99, 98/99 and 99/99 measurements of absolute differences between device and observers within 5, 10 and 15 mmHg for systolic BP (SBP) and 87/99, 98/99 and 99/99 for diastolic BP (DBP), respectively. The average device-observer difference was 1.01 ± 4.11 mmHg for SBP and -0.69 ± 3.56 mmHg for DBP, respectively. The number of participants with two or three of the device-observer difference within 5 mmHg was 28 for SBP and 30 for DBP, and there was no subject with none of the device-observer difference within 5 mmHg.
Conclusion: According to the validation results on the basis of the ESH international protocol revision 2010, the Globalcare GCE603 automated upper-arm BP monitor can be recommended for home measurement in general population.
